Eyie, sleeping a lot and feeling like you describe can be symptoms of depression.
Maybe you can discuss this up with your doctor? If you need them, modern antidepressants can be very effective. If you're already taking them, a dosage change may be worth talking about.
Also, hormone dosages can be out of whack, and you end up feeling really crappy. Another discussion item?
I'm not offering medical advice, just some food for thought. I know there's more to your situation than this, and I hope things turn around for you soon!
